Now we turn to Fish. 34 I can recognize humans. Archerfish hunt by shooting a stream of water at insects.

Researchers have taken advantage of this special skill to test their ability to recognize human faces.

The fish were taught that when they shot water at an image of a specific face on a computer screen, they would receive a snack.
